| 摘 要： | 采用显式四步Runge-Kutta格式，结合Baldwon-Lomax紊流模型求解Navier-Stokes方程，借助运动网格技术，完成了对二维振荡叶栅非定常粘性流动的数值模拟。为了加速求解过程，引入了变系数隐式残差光顺方法，取得了较好效果。数值结果与已公布的数据有很好的一致性。

| Abstract: | Numerical simulations of two dimensional unsteady viscous flow around oscillating cascades are carried out with the four-step Runge-Kutta explicit method and moving grid technique. In order to speed up the calculation, a method called implicit residual smoothing with variable coefficient is applied. It is found that the approach used in this paper is effective, and the computed results are in well agreement with the published data. |
